Solution:

1.(23 / 55) ร 100

2.(10 + 2 + 3 + 4) ร 1000

3.[((25 + 4 + 16) 1000) / ((22 + 10 + 23) 1000)] = 9 :11

4.(16 / 12) ร 100

5.[(22 + 10 + 23 + 12 + 2 + 12 + 10 + 3 + 15 + 25 + 4 + 16) / (22 + 10 + 23)]

6.Required per cent = (89.4 / 14.17) ร 100 โ 72%

7.Required per cent = [(66 – 52.8) / (52.8)] ร100 = (13.2 / 52.8) ร 100
= (1/4) ร 100 = 25%

8.79.2:66 => 6:5 (13.2 is common factor)

9.Required per cent
= (102.23 / 315) ร (100 / 315) ร 100 โ 31.7 โ 32%
